Lu Baolu 9807860f6a iommu/vt-d: Make context clearing consistent with context mapping 
[ Upstream commit 9a16ab9d64 ]

In the iommu probe_device path, domain_context_mapping() allows setting
up the context entry for a non-PCI device. However, in the iommu
release_device path, domain_context_clear() only clears context entries
for PCI devices.

Make domain_context_clear() behave consistently with
domain_context_mapping() by clearing context entries for both PCI and
non-PCI devices.
